Membrane
A high-quality membrane
Cleansui's hollow fiber membrane filters water thoroughly clean. In 1984 Mitsubishi Chemical (then Mitsubishi Rayon) developed a ground-breaking hollow fiber membrane that removes bacteria and rust remarkably well. Today it is highly regarded as a precise filtration membrane and widely used in water purification plants, disinfectant production and medical water.
-
0.01 µm
The secret of advanced removal
The wall of the hollow fiber (polyethylene) efficiently removes particles larger than 0.01 micron (1/100,000 mm), bacteria and iron rust from tap water.
-
4–6 µm
Removes Cryptosporidium
Cryptosporidium measures 4–6 microns, and the hollow fiber membrane removes particles larger than 0.01 micron. Multiplying in the small intestine, it causes stomach pain, fever and severe diarrhea, and chlorine does not kill it.
-
Red rust
Removes red rust
Efficiently removes the red rust often found in the pipes of older buildings.
-
Less clogging
Why it clogs less
The hollow fiber has a mesh-like structure, so it filters not only at the wall but through its inner surface too. That structure is why it clogs less than other makers' membranes.
